Press and hold the FCIM preset buttons 7 and 9 for approximately 10 seconds until the CAL indicator appears in the compass display, then release the buttons.If the CAL indicator does not turn off after the vehicle is driven in a circle at least 5 times, repeat the procedure.
Drive the vehicle slowly at less than 5 km/h (3 mph) in a continuous circle until the C or CAL indicator disappears from the display and the compass heading is displayed.
